Definitions

  • This invention relates to tool inserts.
  • PCD polycrystalline diamond
  • carbide backing a carbide backing
  • Such manufacturers have automatic brazing machines for brazing the tips into pockets on a saw blade.
  • the tips or saw teeth need to be oriented correctly - usually with the PCD facing, down and a chamfered end of the carbide going forward for this brazing operation. Feeding of PCD saw teeth correctly oriented in a reliable manner to the brazing machine is a major headache for saw blade manufacturers.
  • a unit comprises:
  • each insert defining a working region and being adapted to be secured to a tool to present that region with a predetermined orientation
  • each zone having an insert located therein such that the orientation of the working portion of each insert in the zones is the same.
  • the body is elongate in form and the zones are defined along the length of the body.
  • the body will typically take the form of a tape.
  • the zones may be pockets or recesses in the body into which the inserts are placed.
  • the invention has particular application to tool inserts for saw blades which comprise a PCD layer bonded to a carbide backing, the PCD layer providing the working region.
  • the drawing illustrates a perspective view of an embodiment of the invention.
  • a length of tape 10 has a plurality of pockets 12 formed along its length.
  • the tape is coiled on to spindle 14.
  • Located in each pocket 12 is a saw blade tip 18.
  • Each saw blade tip 18 has a carbide backing 20 to which is bonded a PCD layer 22.
  • the PCD layer is formed with a leading cutting edge 24.
  • the carbide backing 20 has a chamfered edge 26.
  • a saw blade tip 18 is located in each pocket 12 such that the cutting edge 24 of each tip 18 is located at the forward end 28 of the pocket and facing down and into the pocket as illustrated.
  • the spindle 14 (which will generally form part of a reel) will be suitably mounted to a saw blade manufacturer's brazing machine.
  • the tape will be moved forward one pocket.
  • a cover tape 30 is simultaneously peeled back from the pocket, exposing one correctly oriented saw blade tip. This is then picked up by a brazing machine attachment and placed into the feeding track of the brazing machine ready for brazing.
  • the tip 18 has been brazed into position, another pocket is moved forward and the process repeated.

Abstract

L'invention concerne une longueur de bande (10) comportant une pluralité de poches (12) ménagées tout au long de ladite bande. Dans chaque poche (12), se trouve une pointe de lame de scie (18), chaque pointe de lame de scie (18) étant accompagnée d'un support en carbure (20) sur lequel est collée une couche de diamant polycristallin (22). Chaque pointe (18) est correctement orientée dans chaque poche (12), un tranchant (24) étant généralement situé sur l'extrémité avant (28) de la poche (12), orienté vers l'intérieur et le bas de la poche (12). Lorsqu'il faut braser les pointes (18) sur une lame de scie, la bande (10) est déplacée d'une poche vers l'avant. Simultanément, une bande de couverture (30) est retirée de la poche (12) de façon à laisser à découvert une pointe de lame de scie correctement orientée (18), laquelle est prête à être immédiatement brasée. Une fois que la pointe (18) a été positionnée par brasage, une autre poche (12) est déplacée vers l'avant et le processus est répété.
